Shodan MCP Server

A Model Context Protocol (MCP) server that provides access to Shodan's internet scanning capabilities through a standardized interface.

Overview

This server implements the Model Context Protocol to expose Shodan's powerful internet scanning and reconnaissance capabilities. It provides a standardized interface for querying Shodan's database of internet-connected devices, services, and vulnerabilities.

Related MCP server: mcp-shodan

Features

• Search Capabilities: Query Shodan's database using advanced search filters

• DNS Lookup: Resolve domain names and get detailed DNS information

• CVE Information: Get detailed information about Common Vulnerabilities and Exposures

• Get Vulnerabilities: Get detailed infor Vulnerabilities related to an IP address

• Standardized Interface: Uses MCP protocol for consistent communication

• Environment Variable Support: Secure API key management through environment variables

Prerequisites

• Node.js (v14 or higher)

• npm (v6 or higher)

• Shodan API key

Installation

1. Clone the repository:

   git clone https://github.com/X3r0K/Shodan-MCP-Server-Inspector.git cd shodan-mcp-server-Inspector

2. Install dependencies:

   npm install

3. Create a .env.local file in the root directory and add your Shodan API key:

   SHODAN_API_KEY=your_api_key_here

Usage

Starting the Server

1. Build the server:

   npm run build

2. Start the server:

   node build/index.js

Available Tools

1. Search Tool

   • Returns: List of matching devices with detailed information

2. DNS Lookup Tool

   • Query: Domain name to resolve

   • Example: example.com

   • Returns: DNS records and related information

3. CVE Info Tool

   • Query: CVE identifier

   • Example: CVE-2021-44228

Example Queries

Using the MCP Inspector

You can use the MCP inspector to interact with the server directly:

1. Install the MCP inspector:

2. Run the inspector with your server:

The inspector provides an interactive interface to:

• Test all available tools

• View tool documentation

• Debug server responses

• Monitor server status

Environment Variables

• SHODAN_API_KEY: Your Shodan API key (required)

• PORT: Server port (optional, defaults to 3000)

• LOG_LEVEL: Logging level (optional, defaults to 'info')

Error Handling

The server implements comprehensive error handling for:

• Invalid API keys

• Rate limiting

• Network issues

• Invalid queries

• Server errors

Security Considerations

1. API Key Protection:

   • Never commit API keys to version control

   • Use environment variables for sensitive data

   • Rotate API keys regularly

2. Rate Limiting:

   • Respect Shodan's API rate limits

   • Implement client-side rate limiting

3. Data Privacy:

   • Filter sensitive information from responses

   • Implement access controls as needed
